When two lines are parallel they have the same slope
so the slope of the parallel line = the slope of the line in the graph= (Y2-Y1)/(X2-X1) = (5-(-7))/(1-(-2)) = 4
Do you understand?
Angle B measures 30 degrees.
Step-by-step explanation:
Step 1:
If two angles are complementary, the sum of the two angles will equal 90°.
So if angles A and B are complementary, the sum of the angles A and B will equal 90°.
It is given that cos A = 0.5, we can determine the value of A by taking the cos inverse of the value 0.5.
Step 2:
If cos A = 0.5, A =
So angle A is 60°.
As A and B are complementary, angle A + angle B = 90°.
So 60° + angle B = 90°, angle B = 90° - 60° = 30°.
So angle B measures 30° while angle A measures 60°.
The perimeter is 72 because all sides on a square are the same measurements so you just have to do 18 times 4 to get 72
